Product Description:

Use any of the flush trimming bits below for laminate work or for template and pattern work. For template application, the bearing follows the template, while the cutting edges trim the workpiece. With the router handheld, the template is on the bottom of the work. With a table-mounted router, the template is on top.
A two-flute bit is a good general-purpose choice, providing fast cuts and good finishes. Excellent for template work.
